Great video! I didn't hear you mention the Splash Apron on the downstream side. For those who are new to this: The splash apron is a row of rocks that is dug into the soil on which you place the first row of rocks (working upstream from there). This row of footer or splash apron rocks prevents the soil from being eroded away by the falling water after it passes over the ORD.
From a retired drainage contractor who built water and sediment control basins, rock spillways, grass waterways, etc but well east of you. Show us results in a year or two.
Thanks for asking and we're glad you're curious about the result. Here is a time lapse that shows the structures in action throughout the first year: czcams.com/video/cfobSpapImA/video.html
@@wygameandfish I see you have been busy - several structures less than 200ft apart for essentially spring runoff. All hand labour? No filter cloth underneath? Vegetation hard to establish and minimum grazing
Water doesn't erode it or wash it out after a growing season or two because the vegetation and fine sediment that fills in the cracks of the One Rock Dam solidifies the whole structure. If built correctly, during high flows water can easily pour over the top of the structure, but the cumulative effect of several One Rock Dam structures working in series spreads the water out of the channel into a thinner sheet flow, which is has less energy/erosive force. Restoring the hydrology to a sheet flow allows the meadow to retain more moisture, grow more productive vegetation, and promote water flows later in the season - through the gradual release of water from the wet meadow "sponge." Awesome, common-sense restoration!
spending most of your budget on cutthroat restoration on rich private property? Yet no fish or budget for hams fork or sweetwater rivers.Utah has much more fish in their rivers,please get some advice .Manage your rivers for license holders ,the trout that can survive and give the most enjoyment to the license holders is the best trout,let the best trout win.
Indispensable practical resource. Thank you

Thanks for the video, it would be AWESOME to see the thing in action by the next rainstorm, and to have a before/after comparison video. Can't wait!
Yes, would love to see what the site looks like after a few months of this great work.
Wonderful !
Thanks for posting.
I wish other Western States did the same.
Great video, thank you!
Great idea!
Awesome!
Old PFC slogan: "keep water on the land longer." The other thing is. That area is very beat up. What's being done to control the grazing access?

what happens when a large flood cuts around the dam? This will cut around the rock dam.
Would a Tesla Valve work for these kinds of "slow water down" projects, or would they be to cumbersome to build or erode away?
I do that on every holiday in France
Hello, beavers! They effectively did this for millions of years!
Beaver are not appropriate for every ecology.
What happens if water erodes it
Water doesn't erode it or wash it out after a growing season or two because the vegetation and fine sediment that fills in the cracks of the One Rock Dam solidifies the whole structure. If built correctly, during high flows water can easily pour over the top of the structure, but the cumulative effect of several One Rock Dam structures working in series spreads the water out of the channel into a thinner sheet flow, which is has less energy/erosive force.

@@nathanseward-dnr8256 Great explanation!
This structure effectively turns the situation from a downward spiral into an upward spiral.
